Publication number: 20240127831Abstract: Conventional audio compression technologies perform a standardized signal transformation, independent of the type of the content. Multi-channel signals are decomposed into their signal components, subsequently quantized and encoded. This is disadvantageous due to lack of knowledge on the characteristics of scene composition, especially for e.g. multi-channel audio or Higher-Order Ambisonics (HOA) content. A method for decoding an encoded bitstream of multi-channel audio data and associated metadata is provided, including transforming the first Ambisonics format of the multi-channel audio data to a second Ambisonics format representation of the multi-channel audio data, wherein the transforming maps the first Ambisonics format of the multi-channel audio data into the second Ambisonics format representation of the multi-channel audio data.Type: ApplicationFiled: October 18, 2023Publication date: April 18, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Oliver WUEBBOLT, Peter JAX, Johannes BOEHM

Patent number: 11895482Abstract: A method for generating loudspeaker signals associated with a target screen size is disclosed. The method includes receiving a bit stream containing encoded higher order ambisonics signals, the encoded higher order ambisonics signals describing a sound field associated with a production screen size. The method further includes decoding the encoded higher order ambisonics signals to obtain a first set of decoded higher order ambisonics signals representing dominant components of the sound field and a second set of decoded higher order ambisonics signals representing ambient components of the sound field. The method also includes combining the first set of decoded higher order ambisonics signals and the second set of decoded higher order ambisonics signals to produce a combined set of decoded higher order ambisonics signals.Type: GrantFiled: January 25, 2023Date of Patent: February 6, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Peter Jax, Johannes Boehm, William G.

Publication number: 20230328462Abstract: In the method according to the invention for actively suppressing the occlusion effect during the playback of audio signals by means of headphones or a hearing aid, a sound signal occurring from outside is captured by means of at least one outer microphone of the headphones or the hearing aid. A voice signal is captured by means of at least one additional microphone. The dry component of the captured voice signal is estimated, the dry component of the captured voice signal being the component of the captured voice signal without reverberation caused by the surrounding space. By means of a filter, a voice component is extracted from the outer sound captured using the at least one outer microphone. The extracted or produced voice component is output by means of a loudspeaker of the headphones or the hearing aid.Type: ApplicationFiled: May 27, 2021Publication date: October 12, 2023Inventors: Johannes FABRY, Stefan LIEBICH, Peter JAX

Publication number: 20230154449Abstract: In the method according to the invention for active noise suppression, a transfer function for a secondary path between a loudspeaker and an error microphone is measured (20). Based on the measured transfer function for the secondary path, a transfer function for a primary path between a reference microphone and the error microphone is estimated (21). Based on the estimated transfer function for the primary path, filter coefficients for filtering to generate the cancellation signal are then determined (22).Type: ApplicationFiled: April 6, 2021Publication date: May 18, 2023Inventors: Johannes FABRY, Peter JAX, Stefan LIEBICH
